⏹ Forbes, James Seald
Forbes, James David

Scottish physicist (1809 - 1868)
Forbes studied law in Edinburgh, then practiced law and left it to work in teaching, so he occupied the professorship of natural philosophy in Edinburgh, and was chosen as a fellow in the Royal Society • Forbes conducted studies on the polarization of heat transmitted by radiation, using crystals of the mineral tourmaline, and also conducted studies on icebergs crawling on the surface of the land (Refrigerators glaciers) He pointed out that the ice moves as if it were a viscous liquid.

⏹ Forssmann, Werner Theodor Alu
Forssman Werner Theodor Otto

German physician ( 1904 - )
Forssmann learned in Berlin, then worked as a surgeon in Aberwalde. One of his important achievements is that he introduced the method of examining tubes into the medical treatment that enters the body through blood vessels to study the heart from the inside. He conducted these dangerous experiments directly on himself.
This method, invented by Forsman, was met with strong opposition and harsh criticism by conservative doctors until 1941, when the American doctor Cornand and Richardsey emerged as understanding and defending this method. These two doctors worked to develop Forsman's method, so they used it and improved it and proved its usefulness and importance.

Stripped of his position, he devoted himself to the study of mathematics, and it is thanks to Forer for discovering a method in mathematical analysis based on the basis that any function of a variable (x) can be decomposed into an infinite series of multiplied sinuses of the same variable. This theory is known as the Fourier Series.
